5-22-10 DOUBLE SIGNED BINARY DIVIDE – DBSL(––)
Limitations
DBS(––) divides the signed binary content of Dd by the signed binary content
of Dr, and outputs the 8-digit signed binary result to R+1 and R. The quotient
is placed in R, and the remainder is placed in R+1.
Note Refer to 1-7 Calculating with Signed Binary Data for more details.
ER: Dr contains 0.
Indirectly addressed EM/DM word is non-existent.
(Content of *EM/*DM word is not BCD, or the EM/DM area boundary
has been exceeded.)
EQ: ON when the content of R (the quotient) is 0000, otherwise OFF.
In the following example, DBS(––) is used to divide the signed binary contents
of DM 0010 with the signed binary contents of DM 0020 and output the result
to LR 21 and LR 02.

Dd and Dd+1 must be in the same data area, as must Dr and Dr+1.
R and R+3 must be in the same data area.
DM 6143 to DM 6655 cannot be used for R.
